IMPROVEMENT IN BED-BOTTOMS.

S pccffication forming part of Letters Patent No. 165,] 66, dated July6, 1875; application filed January 20, 1875. I

To all whom it may concern:

Be it known that I, LIVERUS HULL, of Boston, of the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Bed-Bottoms; and do hereby declare the same to be fully describedsupporting-springs.

In such drawings, A denotes a 'frame composed of two side bars, a a, andthree connection-bars,b b 1), arranged as shown, each of the said barsI) being tenoned into the bars a a. A seriesof conicc-spiral or helicalsprings,

B, have their base-coils arranged on, and fixed to, each of the bars I).Eachof such springs, at its upper coil, supports one of a series ofslats, 0, arranged as represented, and said coil is held up against, andconfined to, the slat by means of a duplex latch-lever, D, formed asshown in the drawings, and pivoted at its middle to that side of theslat against which the end coil of the spring is to bear.

By hooking the coil about the middle part g of the latch-lever andrevolving the lever in the coil, the latter will be drawn hard up to theslat by the two arms h h, the detachment of the coil and slat beingeffected by turning the latch-lever in the opposite way the necessaryextent. These latch-leversI usually apis a pair of the said brace-rodsto each of the said outer cross-bars b b, a top view of one of said rodsbeing represented in Fig. 7, wherein.

it is shown as bent at a right angle near each end, as represented at ee. The two rods of each pair cross each other, as shownin Fig. 3, andare at theirinner ends driven into the bar b. At their other ends suchrods hook into staples f extending from the two outer slats.

A bed-bottom constructed in the above-described manner can easily betaken apart and packed in a small compass for transportation, and it canas easily be set up or put together.

I claim- 1. In the bed-bottom, the rotary duplex. latch D, pivoted atits middle to the side of the slat 0, against which the end coilof thehelical springB is to rest or bear, and applied to such coil, allsubstantially as shown and described.

2. In the bed-bottom, the two pairs of brace-rods G G, arranged andcombined with the base-frame A, the sets of spiral springs B, the seriesof slats G, and their connectionbands E E, all substantially asspecified.

LIVERUS HULL.
